Companion Plants
- Polygonatum odoratum 'Variegatum' (Variegated Solomon's Seal) - Arching variegated stems offer contrasting form and light variegation alongside upright hosta foliage.
- Athyrium niponicum 'Pictum' (Japanese Painted Fern) - Lacy, silver flushed fronds echo the cool tones of 'Krossa Regal' and soften the base of its structure.
- Brunnera macrophylla 'Looking Glass' (Siberian Bugloss) - Silvery leaves and delicate blue flowers provide seasonal interest and pair well with blue hostas.
- Astilbe chinensis 'Visions' (Chinese Astilbe) - Plumed pink flowers and coarse foliage bring texture and color contrast beneath and around the vase shaped hosta form.
- Tiarella 'Spring Symphony' (Foamflower) - Compact, clumping growth and frothy blooms provide a fine textured contrast along shaded paths and borders.
